Default **PLEASE NEED SOME HELP w/1JZ SC400***

Yo i need help with my 1jz sc400. It was already swapped by SNAP Performance in TX. Anyways when i bought my car the speedometer never worked. i've changed to a good working cluster and changed speed sensor. still no worky There is a box under the column that says speed control. Does that have to do anything with the speedometer? What should check next? any help would be appreciated

There's a tach fix on the forum, you just gotta search for it. This is for 1jz swaps.

He means the SPEEDometer, not the tach. Is it manual or auto?

If the swap is auto but going into a 5 speed car you must cut off the speed sensor harness from the GE then you must cut the one on the GTE and solder the GE piece so that it will connect to the sensor on the transmission
